where come , why? neither have reason behind exception nor application appears responsible.

i having issue until created new user run gf , installed recent version of jdk 1.8 (i'm running linux os)

i created user: gfadmin

create new user: useradd -d /home/gfadmin -g staff -s /bin/bash gfadmin

then downloaded jdk 1.8.0_91 oracle: (get appropriate tar.gz file os , hardware) http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html

place tar.gz file in /home/gfadmin

gunzip , un-tar file. should create directory:

/home/gfadmin/jdk1.8.0_91 

edit gfadmin users .bash_profile file , add these 3 lines:

java_home="/home/gfadmin/jdk1.8.0_91" path="$java_home/bin:$path" export java_home path 

source .bash_profile:

. ./.bash_profile 

confirm you're using version of java installed, 1.8.0_91:

java -version
